Apparatus and method for reducing energy consumption by cellular base stations

摘要

A method for reducing energy consumption of a base station is described. A first pilot channel is transmitted via a first antenna using a first downlink power amplifier. A second pilot channel is transmitted via a second antenna using a second downlink power amplifier. It is determined that no multiple-input and multiple-output users are in a cell corresponding to the base station. The second pilot channel is shut off.

1. A method for reducing energy consumption of a base station, comprising:
communicating with one or more user equipments using n carriers; determining that a load of one or more of the n carriers is below a carrier load threshold; redirecting one or more user equipments from the one or more carriers with loads below the carrier load threshold to one or more other carriers; and turning off the one or more carriers with loads below the carrier load threshold.
